1. All peripherals OFF, VDD from 1.65 V to 3.6 V, HSI internal RC osc., fCPU = fSYSCLK

2. For devices with suffix 6.

3. For devices with suffix 7.

4. For devices with suffix 3.

5. Flash is configured in IDDQ mode in Wait mode by setting the EPM or WAITM bit in the Flash_CR1 register.

6. Tested in production.

7. Oscillator bypassed (HSEBYP = 1 in CLK_ECKCR). When configured for external crystal, the HSE consumption

(IDD HSE) must be added. Refer to Table 31.

8. Oscillator bypassed (LSEBYP = 1 in CLK_ECKCR). When configured for external crystal, the LSE consumption

(IDD HSE) must be added. Refer to Table 32
